Cascaded H-bridge Multilevel Inverters -A Reexamination

2007 IEEE Vehicle Power and Propulsion Conference, 2007
Multilevel converters have gained popularity in high-power applications due to their low switch voltage stress and modularity. Cascaded H-bridge converters are a promising breed of multilevel converters which generally require several independent dc sources. Recently, existence of a redundant switching state has been utilized to replace the independent

Cascaded H-Bridge Multilevel Inverter Using SVPWM Modulation

2019 1st International Conference on Advances in Science, Engineering and Robotics Technology (ICASERT), 2019
In grid connected renewable energy generation system, using converter is a must. For this purpose, we proposed a multilevel H-bridge inverter that will contain lower third harmonic distortion. To achieve this target, higher number of output voltage level is necessary.

Quasi Cascaded H-Bridge Five-Level Boost Inverter

IEEE Transactions on Industrial Electronics, 2017
Latterly, multilevel inverters have become more attractive for researchers due to low total harmonic distortion in the output voltage and low electromagnetic interference. This paper proposes a novel single-stage quasi-cascaded H-bridge five-level boost inverter (qCHB-FLBI).
